Arcuate depressions 'are formed-iinthe proximate ends of the slides 'I and thefpoint's'of the cam5 turn in'these'a'rcuate depressions when'thefhandle 4ris moved up or down.

The shaftl of cam 54 passes through the body fwhichrismade-hollow for' the reception of slides 91Which are sec-ured'to andform a part of the slides-11;` Springs l0 rest again'st the end of the members 9 and against the closed ends H' of," the body 81. Therefore, when the handle or lever' 4` isfturnedfup through' substantially ninety degrees (909); thelcam E'is turned into a horizontal position, and-this permits thefslides-'I' to befiorced invvardlyby` the springs H32 The'slides 1 arevprovided adjacent their ends with brackets Hand v IF3'for reception of the screws. I4. These screws.; are` normally securedagainst endwise movement in the bracketsl butl have` screw- 'threaded connectionw-ith the slides! 5, thus inak-V ing it possible to adjust thev vertical over-all dimension of the coils. However, whenv a set of coils hasl been wouncl'andfit is desired to" remove" head, will be exactly the same dimension as l those previously wound. However, if it islnecessary to change the size of the'coils; this canbe j done by adjusting the screws i4 to adjust the slides I5 longitudinally of the screws. Each spool I6 is made lup of two units whichwemay refer toV x as upper and lower units. next be described. Body members, or wire-receiving units, I8 rare grooved for the reception of triangular shaped Webs I9 carried by guide members or carrying units 20, arranged to be adjusted relatively toward and from each other, as shown in Fig. 6, by means of a right and left hand threaded member 2|, secured against movement longitudinally through the block 22, the location of which will be seen in Fig. 2. Guide members 20 are provided with holes 2|a for the reception of screws 2|, as seen in Figs. and 11. provided along their lower edges with iianges 23, as indicated in Fig. 10, which serve as guiding means for the blocks or body members I8` when being adjusted toward and from each other. Each of the blocks I8 is grooved along one extremity, as indicated in Figs. 1,12,'and 5, to" provide anges 24 between which the wire may be Wound. y

The stepped block or bracket 25 shown in Fig. 12, is united by its edge 2B with a block or slide l5 and, therefore, as these slides move toward and from each other, the stepped blocks 25 also move toward and from each other, carrying with them the body members I8. This movement may be caused by turning cam -5 or screw |4. 'However, it is possible, by means of the screws'Z'Lindependently to adjust the spools I6 with relation to the blocks or brackets 25. This is by relatively adjusting the guide member andthe block 25,

as best illustrated in Figs. 2 and 6. The screws 2| pass through blocks 22 and holes 2|a in guide members 20. It is thereforel clear that there can The guide members 2|) are These two units ing the size of the coils wound on the spools. The amount of this vertical adjustment, by adjustment of the screws 21, is not great, but a considerably larger adjustment can be secured by turning the screws 2| so as to increase or decrease the lateral width across the blocks I8 which, as stated above, slide on the flanges 23, as shown in Fig. 6.

Alloi the spools I6 are provided with screws 2'| for adjusting the vertical dimension of each spool, except the smallest one Ia, the one at the left in Fig. 1, which is not provided with transverse adjusting means 2|, as is clear from Fig. l. As shown in Figs. '7, 8, and 9, this unit "is constructed dierently from the others. These end spools are denoted by the numeral Ilia to distinguish them from the spools I6. Each comprises a block 3| and a cover plate 32, the two being held together by ascrew or screws 33, passbe no relative vertical movement between parts I8, i9, and 20. Itis also clear that there can be no relative movement between blocks 22 and 20, although there may be movement between parts 20 and 25. 9

Holes 28 pass through the stepped blocks 25, from side to side, to allow for the requisite relative movement of the blocks and the screwthreaded members 2| which are located in the holes 28. Screw-threaded holes 29 pass through the treads of the steps of the' blocks 25 into the holes 28, as'shown most clearly inv Fig. 12. Therefore, since the screws 21 are held against longitudinal movement inthe holes 30 of guide members 20 and have screw-threaded connection with blocks 25, the blocks 20 and 25 willy be caused to have relative vertical movement with reference to each other when the screws 21 are turned. Hence, since blocks 25 are secured to orlform a part of blocks I5 and can move only as the latter are moved, the assembly comprising IB, I9, 20, 2|, and 22 must move relatively to blocks 25. This is for the purpose of independently adjusting through a hole or holes 34. This means is provided for drawing the block'and cover plate together whereby to clampl lthe arcuate members 3l between them, the latter being slightly thicker than the space allowed for them between the cover plate 32 and the bottom of the groove in the block 3|. Channels 35 are formed in the block 3|, either inside or outside of the channels in which the arcuate members 31 travel. These are for the reception of the fingers 36 formed on the outside or inside of members 31, which fingers serve as stops to prevent members 3l from` being withdrawn from the channels whenbeing adjustedinto position for adjusting the width of a coil formed thereon. Such position is shown at the left in Fig. 9. Normally thev blocks 3| are formed integrally with the stepped blocks 25.

vWhile Fig. 9 shows one way of constructing this unit, it is by no means the only way, as we have devised others for accomplishing the intended purpose, which is to permit adjustment ofthe size ofa coil formed upon this unit. Likewise, other parts may be made differently than shown in these drawings without departing from the spiritfof this invention as disclosed herein and as set forth in the appended claims.

' Having'now described our invention, we claim:

1. In ka structure for the purpose stated, supporting means for slides, said supporting means being hollow and serving as a housing for springs, springs in said housing,v slide members in said housing actuated toward each other by said springs, portions of said slide members being outside of said housing and sliding longitudinally thereof, operable means extending through said housing and having a cross-head located between the adjacent ends of said portions for causing longitudinal recprocation thereof upon operation ofjsaid operable means, brackets carried by said portions and projecting approximately horizontally ,away therefrom, and wire receiving blocks vadjustably carried by said brackets.
